Management of Chronic Noninfectious Uveitis with Low-Dose Methotrexate
Abstract Purpose To evaluate the effectiveness of low-dose oral methotrexate(5mg/week) among chronic noninfectious uveitis patients who were unresponsive to conventional steroids therapy. Methods 27 patients with chronic noninfectious uveitis who were treated with low-dose methotrexate (MTX) at ophthalmology department of Pyongyang University of Medical Science Hospital from 2017 to 2020 were participated in this study.Each patient received oral MTX at dose of 5mg/week except that 2 patients were given 7.5mg/week MTX for the first 4 weeks. The treatment effects were evaluated based on ratio of inflammation control, Log MAR visual acuity, mean number of relapses and steroid-sparing effect. Every adverse effect associated with drug use was recorded. Results Control of inflammation was achieved in 92.6% of patients. Visual acuity was improved in 82.9% (29 eyes among 35 eyes) and maintained in 5.7% (2 eyes). The mean number of relapses was decreased from 4.2 (before therapy) to 1.9 (after therapy). Steroid-sparing effect was achieved in 85.2% patients. There was no serious side effect requiring discontinuation of therapy but some adverse reactions were recorded in 22.2% of patients. Conclusions Low-dose methotrexate(5mg/week) is supposed to be able to successfully control chronic noninfectious uveitis and has a steroid-sparing effect. It is also safer because it shows less adverse effects.
